概括
在毒素诱导的发作中,性泄露很少发生,电脑电图 (EEG) 很少改变抗药物管理. 这项研究分析了83名因药物诱导的而住院的患者的EEG发现.
科学领域:
- 神经学 神经学
- 临床神经生理学 临床神经生理学
背景情况:
- 与相比,毒素诱导的发作具有独特的挑战,通常需要脑电图 (EEG) 来排除非性状态 (NCSE).
- 在毒素诱导的中特征EEG发现对于理解它们的特定神经生理学影响和指导患者管理至关重要.
研究的目的:
- 为了确定患有毒素诱导的发作的患者在EEG上的发作的频率.
- 在这个人群中评估非状态 (NCSE) 的发生率.
- 评估EEG发现是否影响开始服用抗发作药物 (ASM).
主要方法:
- 从2013年至2022年期间因药物诱导的而住院的16岁以上患者的83个EEG记录的回顾性审查.
- 排除标准包括先前的史和EEG之前的心脏骤停.
- 主要结局:发病发病率;次要结局:增加了EEG后的ASM.
主要成果:
- 在53%的EEG中观察到普遍减速.
- 在只有2.4%的病例中检测到型活动.
- 没有发现NCSE的病例,并且在患有型出院的患者中没有启动ASM.
结论:
- 在毒素诱导的发作的情况下,性泄漏并不常见.
- 在这些情况下,常规EEG发现主要显示普遍减速,而不是急性形异常.
- 在毒素诱导的中,EEG结果很少导致抗药物管理的变化.

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
